This product is an audio quality-improving seal for optical discs,
utilizing an organic polymer hybrid damping material with the highest
level of vibration-absorption performance.
Simply apply the 0.3-mm thick ring-shaped seal to the center of a CD,
DVD, or other optical disc to absorb the minute levels of unnecessary
vibration generated during playback with amazing efficiency, and greatly
attenuate the physical and electrical noise caused by this vibration.
This makes the sonority, spread, thickness, and subtlety of the sound
extremely true to life, dramatically improving the ability to reproduce
the original sound. Additionally, the center (remaining) portion of the
ring-shaped seal can be used to remove remaining adhesive, or to tune
the device.

The number of DS-25 rings has been increased from 11 to 18, thus reducing the unit cost.
Not only that, but further advancements have enhanced the sound quality and enabled a higher level of fidelity.

USAGE

Be careful not to cut yourself with the plastic spatula when removing
it from the case or using it to peel off or apply the seal.

? When removing the seal from a disc, be sure to completely remove any
remaining adhesive. If adhesive from the seal remains on the disc, then
the audio device could become damaged the next time the disc is played.

? When removing adhesive from a disc, you can use the remaining center
portion from the seal ring. Press the adhesive portion of the seal to
the disc several times; this will cleanly remove the adhesive.

Peel off the seal by using the plastic spatula.

Put the seal on the center of the case with the adhesive face of the seal upturned.

Put the disc on the case with the label said downward ,and firmly press the seal.

About High Damping Material fo.Q

‘fo.Q′ is a product applying materials developed with the support of JST (Japan Science and Technology Agency). Vibrational energy is converted to electric energy, and finally to heat energy, enabling efficient absorption. There are no rubber or heavy metal overtones, and efficient attenuation of the finest vibrations,considered difficult to remove up to now, promise you the purest and clearest tones.

Damping performance of ‘fo.Q′

The
graph to the left shows the difference in damping when ‘fo.Q′ is
adhered to metal products, and the same level of vibration is applied.
Using ‘fo.Q′ makes it possible to dampen the vibration of materials much
more quickly than when it is not used. This benefit quickly and
efficiently dampens the vibration of audio equipment, improving the
audio quality and raising the signal-to-noise ratio.

Comparison of damping performance with ‘fo.Q′ and conventional damping materials

The
damping material used in ‘fo.Q′ has at least twice the damping
performance of conventional damping materials.Additionally, with
conventional damping material, damping performance falls as strain
decreases, ultimately reaching zero. In contrast, the damping material
used in ‘fo.Q′ features the property that as strain decreases, damping
performance increases. These properties enable ‘fo.Q′ to quickly and
efficiency damp the minute vibrations generated by audio equipment,
making it possible to enjoy clear, flowing audio.

Loss factor is a measure of damping performance. The higher the loss factor, the better the damping performance is. Here the term “strain” refers to the vibration itself; it does not refer to strain in the audio.

‘fo.Q′
audio boards have an average of 10 times the damping performance of
conventional inorganic boards over the entire frequency band. In the
low-frequency band (300 Hz and below) and the high-frequency band (4,000
Hz and above) in particular, the damping performance is extremely
high.These effects enable ‘fo.Q′ to dramatically dampen low and
high-frequency noise in particular, clarifying the contours of once
difficult-to-hear audio. It also eliminates distortion when audio is
played at high volumes.
